of a molecular trefoil knot in
90% overall yield through the self-assembly of a 12-component trimeric
circular zinc helicate followed by ring closing metathesis of six
pendant alkene chains. Both the trimeric circular helicate intermediate
and the resulting trefoil knot were characterized by NMR spectroscopy,
mass spectrometry, and X-ray crystallography.
